I dont think I am going to be able to connect to LDAP for every
connection. I have atleast 3000 pop and 1000 concurrent imap connections
on the server. 




One more issue with nginx 0.8.34  is that when auth-fails on the real
server the nginx returns "BAD: internal server error" 
The email clients are not able to interpret this error. 

Can I configure nginx to pass on the actual message from my cyrus server
"NO LOGIN failed" 

Thanks
